how to find number perfect square

Given a positive integer num, write a function which returns True if num is a perfect square else False.Note: do not use any built-in library function such as sqrt .Example 1:Input:16returns:trueExample 2:Input:14returns:falseCredits:Special thanks

TopicGive a positive integer n to find several complete squares (e.g. 1, 4, 9, ...) Make their sum equal to N. You need to have the fewest number of squares.Sample ExampleGive n = 12 , return 3 because 12 = 4 + 4 + 4 .Give n = 13 , return 2 because 1

We know that any element in an array can be accessed within an O (1) time by direct addressing via an array (directly addressing). Therefore, if the storage space allows, you can provide an array, for each possible keyword to maintain a location,

As mentioned above, in addition to classification algorithms, the feature extraction algorithms for processing classification texts also have a huge impact on the final effect. Feature Extraction algorithms are classified into feature selection and

Given a positive integer n, find the least number of perfect square numbers (for example, 1, 4, 9, 16, ... ) which sum to n. For example, given n = 12 , return 3 because 12 = 4 + 4 + 4 ; given n = 13 , return 2 because 13 = 4 + 9
